Product Description

Marsh 40 mm and 50 mm liquid filled severe service gauges are expressly designed to provide reliable pressure measurements in harsh and demanding industrial and OEM environments, particularly where pulsation and vibration are a concern. The gauges are filled with glycerin to offer a dampening effect, while reducing pointer flutter, as well as offering significant shock reduction to instrument-grade components. They also lubricate internal components, effectively reducing risk of corrosion. The liquid-filled gauges feature a ventable top fill plug and can be mounted on either a horizontal or vertical plane. Units are hermetically sealed for reliable operation in harsh or dirty environments, while reducing the chance of leaks and ease of refilling in the field.
